Title: Method and apparatus for producing negative and positive oxidative reductive potential (orp) water
Inventor: SUMITA OSAO
IPC: C02F1/461
Filed: 2002-12-05
Abstract: A method and apparatus for electrolytically producing oxidation reduction potential water from aqueous salt solutions for use in disinfection, sterilization, decontamination, wound cleansing. The apparatus includes an electrolysis unit having a three-compartment cell (22) comprising a cathode chamber (18), an anode chamber (16), and a saline solution chamber (20) interposed between the anode and cathod chambers. Two communicating (24, 26) membranes separate the three chambers. The center chamber includes a fluid flow inlet (21a) and outlet (21b) and contains insulative material that ensures direct voltage potential does not travel through the chamber. A supp ly of water flows through the cathode and anode chambers at the respective side s of the saline chamber. Saline solution flows through the center chamber, either by circulating a pre-prepared aqueous solution containing ionic species, or, alternatively, by circulating pure water or an aqueous solution of,e.g., aqueous hydrogen chloride and ammonium hydroxide, over particulate insulative material coated with a solid electrolyte. Electrical current is provided to the communicating membranes separating the chambers, thus causin g an electrolytic reaction that produces both oxidative (positive) and reducti ve (negative) ORP water.

Title: Low sediment process for thermally reacting highly reactive polymers and enophiles
Inventor: SPENCER JEREMY ROGER
IPC: C10L1/198
Filed: 2004-06-18
Abstract: A process for forming an ene reaction product wherein an enophile, such as maleic anhydride, is reacted with reactive polyalkene having a terminal vinylidene content of at least 30 mol%, at high temperature in the presence of a free radical inhibitor. The polyalkenyl acylating agents are useful per se as additives in lubricating oils, functional fluids, and fuels and also serve as intermediates in the preparation of other products (e.g., succinimides) useful as additives in lubricating oils, functional fluids, and fuels. The presence of the free radical inhibitor during the high temperature reaction results in a reaction product that is low, or substantially free from sediment.

Inventor: STARTSEV VLADIMIR
IPC: H04J3/16
Filed: 2005-02-02
Abstract: In a PBX environment, a middleware module abstracts communication cards so that the plurality of channels associated therewith are grouped for efficiency. The middleware module recognizes unoperational channels, and restarts the hardware associated with the channels as well as allowing conferencing and transferring calls when the PBX switch does not support same. Preferably, for outgoing calls, the middleware adapter controls the state of interfaces for all hardware adapters and tries to deliver calls over active interfaces. In case of failure, the middleware adapter investigates and makes a decision if the call should be delivered over another adapter. In this way, redundant and highly available solutions are implemented transparent to application and interface drivers. For incoming calls, the middleware adapter accepts calls from all hardware adapters and presents these calls to applications as if these calls are issued by one adapter.

Filed: 2005-03-10
Abstract: The present invention discloses a submarine observation system in which a plurality of carrier lights assigned to each submarine observation equipment is transmitted from a land terminal apparatus to an optical submarine cable (down-going) by using a WDM transmission. In the submarine observation equipment, only a prescribed carrier light is demultiplexed by an optical demultiplexer, an observation signal indicating an observation result is generated by an observation device, intensity of the carrier light demultiplexed by the optical demultiplexer is modulated by an optical amplifier based on an observation signal, and the modulated carrier light is multiplexed by an optical multiplexer. The multiplexed carrier light is output to the optical submarine cable (up-going) to be returned to the land terminal apparatus being the transmission station. The land terminal apparatus is able to obtain an observation signal of each observation point by separating carrier lights based on each wavelength and receiving a separated carrier light of each wavelength. Accordingly, the system can be structured with one optical fiber and can be extendable by increasing or decreasing carrier lights, and either one of the land terminal apparatuses can receive an observation signal even when the optical submarine cable is cut off.

Title: Hydrogen concentraton sensor for an electrochemical fuel cell
Inventor: BARTON RUSSELL H
IPC: H01M8/04
Filed: 2005-03-24
Abstract: In a hydrogen gas line where the composition of the gas is primarily hydrogen, impurities present in the gas line will typically reduce the speed of sound. Accordingly, an acoustic sensor can be used in such a hydrogen gas line to indicate when impurities have accumulated in the gas line. In particular, the hydrogen gas line may be in a fuel line for an electrochemical fuel cell system. The sensor may comprise transducers, more particularly piezoelectric transducers, as both sound detectors and/or sound generators. Further, the sensor can measure either the speed or frequency of sound to determine the hydrogen concentration. If the fuel is recirculated back to the anode inlet, such a hydrogen sensor in the anode exhaust may be used to determine when it is beneficial to purge the anode exhaust to the external atmosphere.

Title: Preparation for external use on skin
Inventor: TSUNETSUGU SHUICHI
IPC: A61K31/375
Filed: 2005-05-20
Abstract: The present invention has as an object to provide a preparation for external use on skin in which a water-soluble ascorbic acid can be stably dissolved. By blending a low molecular weight betaine in a preparation for external use on skin including a water-soluble ascorbic acid and a glycol ether or a specific polyhydric alcohol, the water-soluble ascorbic acid can be stably dissolved. For this reason, a preparation for external use on skin in which a water-soluble ascorbic acid can be blended in a high concentration can be produced, and therefore, the various effects which ascorbic acid inherently possesses can be effectively exhibited depending on the blending amount thereof. In addition, a preparation which does not give a sticky sensation after applying to the skin, provides a moisturizing sensation, and provides good fitness to the skin, can be produced.
